Note: In this article, the example projects use the Code Base - LED Bumper Top GO Build.

How the LED Bumper is Used

The LED Bumper is used to detect physical contact and display colors. When the LED Bumper is pressed, it can be used to trigger a behavior. For example, the LED Bumper can be used to start or stop the Drivetrain when pressed.
